TYPE-WRITER TYPE-CLEANER.

Specification of Letters Patent.

ratentea May c. 1919.

application filed February 20, 1919. Serial No. 278,260.

To all whom it may concern:

Be it known that 1, JOHN P. WILSON, a citizen of the United States, residing at .ltockville Center, in the county of Nassau, State of New York, have invented certain new and useful Improvements in Type- Writer Type-Cleaners, of which the following is a specification, reference being had to the accompanying drawings, forming a. part thereof.

My invention relates to devices for cleaning the types of typewriters and relates more particularly to such cleaning devices which are adapted to be attached to the typewriting machine.

An object of the invention is to have a cleaning device, such as a suitable brush, ever ready, attached to the machine, which the operator can always find, so that she can readily and quickly clean the type without soiling her hands. Other objects of the invention are effectiveness in operation, simplicity of construction, inexpensiveness of manufacture, adaptability to different makes of typewriting machines, durability, reliability, and other objects and advantages which will hereinafter appear.

My invention includes features of construction and combinations of parts, as will appear from the following description.

1 shall now describe the typewriter type cleaner embodying my invention illustrated in the accompanying drawings, thereafter point out my invention in clalms.

Figure 1 is a front elevation of the type cleaner shown as attached to a typewriter, parts only of the frame of which are illustrated in the drawings, the type cleaner be ing shown in full lines in the position for use, and being shown in broken lines in the non-operative position.

Fig. 2 is a perspective view of the complete type cleaner, separate from the typeshown in the non-operative position of the parts thereof.

Fig. 3 is a transverse section on a plane indicated by the line 33 of Fig. 2, as viewed from the left, and shows more particularly the hook for detachably support- .ing the brush at the non-operative position thereof.

In Fig. 1 of the drawings, there is illustrated, in addition to the typewriter type cleaner embodying my invention, parts of the frame of a front stroke typewriter shown as comprising an upper transverse and shall front rod or bar A, a lower frame part B, and immediately above this and beneath the rod A an arcuate bank of type C.

The type cleaner illustrated in the drawings as an embodiment of my invention includes a type cleaning device shown as a brush having bristles 1 and a back 2 provided with a short forwardly projecting handle 3. In the construction shown in the drawings, the several arts of the device for operatively supporting the type cleaning brush upon the typewriter are shown as formed of sheet metal. This type cleaning brush is rigidly supported upon the outer end of an outer bar member 4 provided at its outer end with a brush-engaging split clamp, comprising a clampmember 5 which is 'shown as formed in the same piece with the bar member a, and a clamp member 6 which is detachably secured to the bar 4: by means of a screw 7 The outer brush-holding end of the clamp members 5 and 6 are shown as of hook shape and as slightly notched into the edges of the brush back 2, so as firmly-to secure the brush back to the outer end of the bar member 4:, andatithe same time providing for the ready removal and renewal of the brush when the bristles 1 become worn out.

The outer bar member 4 at its inner end part has a longitudinally sliding engagement with theouter end part of an inner bar member 8, this sliding engagement being provided by means of a pair of lateral inwardly turned lugs 9 on the inner end of the outer bar member 4:, and by a similar pair of oppositely inwardly turned lugs 10 on the outer end' of the inner bar member 8, as clearly appears in Figs. 1 and 2 of the drawings, so that the bar members 4: and 8 together form a freely extensible supporting bar for the type cleaning brush.

The inner end of the inner bar member 8 has formed thereon a split eye 11 which has universal pivotal engagement in a supporting eye 12 shown as formed upon one of the members 13 of a split clamp to which the other. clamp member 14 is detachably secured by means of a screw 15. This split clamp, formed by the clamp members 13 and 14 and screw 15, is adapted firmly to engage the crossbar or rod A of the typewriter frame, as shown in Fig. 1, for thereby securing the entire device upon the typewriting machine. In the case of some typewriters not having the cylindrical top rod 16, provided with means for supporting the brush in the nonoperative position out of the path of movement of the types C, and as is indicated in broken lines in Fig. 1, and as shown in in full lines in'Fig. 2. The outer end of the brush supporting arm 16 is provided with a forwardly projecting supporting hook 17, upon which the flat lower side of the outer end of the outer bar.

member 4 is adapted to rest adjacent to the 1 brush back 2, as shown most clearl in Fig.

adapted slightly to 3. This hook 17 at the rear, ad acent to the outer end of the arm 16, is provided with a forwardly projecting rounded lug 18 overhang the rear edge of the bar 4, and of the shank part of the clamp member 6, as shown in'Fig. 3, for thereby prevening accidental disengage ment of the brush-supporting arm 4 from the hook 17, as will be readily understood.

In order to disengage the brush-carrying bar member 4 from the supporting hook 17 having the retaining lug 18, it is only necessary to impart a rocking movement to the brush by raising up the outer end of the brush handle 3, thereby permittin the disengagement of the rear edge 0 the bar member 4 from beneath the retaining lug 18, as will be clear from an inspection of Fig. 3. With the hand of the operator still grasping the handle 3, the brush may now be lowered to the operative position, shown in full lines in Fig. 1, and may be moved freely back and forth over the type C for effectively cleaning the latter.

The universal joint pivotal connection of the upper end of the inner bar member 8 with the supporting eye 12 of the clamp member 13 not only provides for unrestricted type-cleaning movement of the brush but also further provides for the engagement of the brush with the type C regardless of whether or not the type may be located exactly in a vertical plane below the upper frame rod A. This universal connection also further provides for ready engagement and disengagement of the outer brush-carrying end of the outer bar mem-' ber 4-with the brush-supporting hook 17, as will be readily understood.

The longitudinal sliding relation between the outer bar members 4 and 8 provides for applying effective type-cleaning pressure of the bristles l of the brush upon the type C.

Also this freely extensible relation between located at a greater or at a less distance from an upper supporting frame part, such as the rod A. Furthermore, this extensible relation of the connected brush-carrying bar members 4 and 8 provides also for the effective cleaning of the arcuate bank of type C, regardless of whether or not the center of this are shall be located coincidentally with the pivotal point of the upper pivoted end of the inner bar member 8, which of course is at the center of the supporting eye 12. In any case the supporting eye 12 should be located above and substantially midway between the ends of the curved bank of type C, as shown in the drawings.

hen not in use the type cleaning brush,

- together with its extensible supporting bar member, is supported upon the hook 17, the rounded lug 18preventing accidental disengagement from this hook such, for example, as might occur from the vibration of use of the typewriter.

It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described within the principle and scope of my invention.

I claim:

1. A typewriter type cleaner having, in combination, a supporting member adapted to be located above the type and to be attached to a front part of the frame of a front stroke typewriter, a cleaning device adapted to be moved back and forth from side to side over the type, and means pivotally connecting the cleaning device with the supporting member above and intermediate the ends of the bank of type.
